The aim of this study is to reveal differences between attitudes and approaches of
students from different types of high school and the first grade of university towards
problem solving in chemistry. For this purpose, the scale originally developed by Mason
and Singh (2010) to measure students’ attitude and approaches towards problem
solving in physics (AAPS), was adapted for chemistry. The Attitudes and Approaches to
Chemistry Problem Solving (AACPS) scale included Likert-type items and was conducted
with 552 students from science (2), regular (2), and vocational (2) high schools, plus one
university. No statistically significant difference were found among high schools, but
there was between high school and university students, and between female and male
students in terms of their attitudes and approaches towards problem solving in
chemistry. University students demonstrated more expert-like attitudes towards
problem solving, and science and regular high school students were similarly expert-
like, while the vocational high school students were rather novice-like. The results
obtained through the AAPS physics attitude scale conducted in the same sample group
were compared with results of the chemistry scale. Variances between these attitudes
and approaches towards problem solving in both chemistry and physics were analyzed
and some suggestions made.
Keywords: chemistry teaching, problem solving, attitude scale, expert-novice problem
solvers.
INTRODUCTION
Recent developments in science and technology have predominantly emerged in
the field of chemistry, which is one of the most significant disciplines of science.
Undoubtedly, an effective science education is vital so as not to let students fall
behind these rapid developments and in order to raise individuals who are open to
advancements, have the ability to keep pace with new developments, undertake

research, and are able to enquire, produce something new, and have a good level of
self-confidence. Therefore, the main objective of chemistry education is defined as to
have knowledge and understanding about the basic concepts relevant to substances,
the interactions between substances, and to raise awareness about historical
development of these concepts and their effects on individual, social, economic and
technologic worlds, as well as the relation with the natural environment (TTB,
2007).
Chemistry is a difficult subject to learn (Markow & Lonning, 1998; Scudder,
1997), because students mostly encounter physical phenomena in their daily lives
rather than chemical ones (Hand & Treagust, 1991). For instance, in physics,
students may easily correlate moving objects by using the force concepts and in
biology, understand the growth of plants taking nutrients from the soil and energy
from the sun. As Taber (2001) also argues, chemistry, contrary to biology and
physics, does not provide a comprehensible structure in the mind about new
experiences that are encountered every day. This abstract side of chemistry results
in parrot fashion learning rather than conceptual comprehension (Gabel, Samuel, &
Hunn, 1987). Although there are many methods offered by researchers in order to
learn chemistry well (e.g., laboratory activities, IT, multimedia etc.), for the
permanence of this knowledge, namely to become an expert in chemistry, a
cognitive structure of the basic knowledge, problem-solving skills and expert-like
approaches and attitudes are required.
There is already agreement among researchers regarding the fact that positive
attitudes significantly affect students’ success in science classes (Ayyildiz, 2012).
Students’ attitudes and approaches towards learning science are of as much
importance as their academic success. Ramsden (1998) regards “science” as an
umbrella concept and emphasizes that it contains biology, chemistry, physics, and
other relevant fields. The same researcher also claims that studies on students’
attitudes should be examined separately for each of these fields; partly because the
positive attitude of (especially female) students towards biology is a well-known
fact.
There are studies about students’ attitudes towards the sciences (physics,
chemistry, biology) within the literature. Some of these studies with attitude tests
suggest a high correlation between this positive attitude for chemistry and the
success of students (Simpson & Wasik, 1978; Soyibo, 1985; Wilson, 1983).
Moreover, some gender-related studies suggest that male students have more
positive attitudes towards chemistry, while others claim the same result for females.
The first study about the effects of gender on secondary school students’ attitudes
towards chemistry was conducted by Hofstein, Ben-Zvi, and Samuel (1977), with the
scale developed by Tamir, Arzi, and Zloto (1974), basically for the subject of physics,
adjusted and used for chemistry. 300 students from 11th and 12th grades were
applied the attitude scale which is composed of 76 items, which resulted in a
determination that female students had more positive attitudes towards chemistry
than males.
Not many studies have been conducted in a class environment that are relevant
to students’ attitudes towards chemistry. Such kinds of studies are mostly concerned
with ‘science’ as an umbrella subject area. Hofstein et al. (1977) determined that
positive attitudes of students towards studying chemistry decrease when they start
the 12th grade. However, Menis (1989) states that 12th grade students have more
positive attitudes than do 11th grade students. It is also a well-known fact that
students’ attitudes and approaches towards learning significant affect what they
really learn.
Problem solving methods would improve cognitive levels of students and enable
them to comprehend any subject in a better way. Comprehension of the subject and
achieving success in chemistry are only possible through a full knowledge of the
820 © Author(s), International J. Sci. Env. Ed., 11(5), 819-837
Students’ attitudes and approaches to problem solving in chemistry
relevant chemistry subjects and being expert in chemistry problems, even though
some of them are hard to solve. If a student does not have a holistic perspective on
chemistry subjects and approach them as independent and irrelevant subjects from
one another, they cannot compile knowledge in a specific hierarchy, and so cannot
solve the problems. Some students think that physics (and likewise chemistry) is a
subject only suited to clever and intelligent people, that teachers are the only
authority within the class and that students should only listen to instruction, take
notes, and learn rote-fashion in order to pass exams. Should they do this, they will
likely fail to grasp the core knowledge of the subject, and most probably not be able
to analyze and synthesize the subject, not enquire to understand the realities behind
the rules of chemistry through a cause-effect relationship, and will ultimately limit
their knowledge to superficial information (Gray, Adams, Wieman, & Perkins, 2008;
Redish, Saul, & Steinberg, 1998).
Teachers can help students to develop their attitudes and approaches towards
problem solving by implementing certain explicit teaching strategies in lesson plans.
First of all, a modeling, which means that the instructor demonstrates and
exemplifies the skills that students should learn, may be obtained by providing
knowledge and skills through illustrations regarding chemistry problems. They may
conduct coaching throughout the implementation and practice process, and then
wean off this relation to help them gain self-confidence and stand on their own two
feet (Collins, Brown, & Newman, 1989).
Attitudes and approaches towards effective learning impact the way students
learn, the time they spend in preparation, and the way they organize their current
knowledge in the field within this process. If the teacher is unaware of students’
attitudes and approaches towards problem solving, time and effort could be wasted
through employing the wrong strategies for the students’ development. Students
mostly start solving problems with a superficial approach, applying their basic
knowledge of mathematics and basic formulas, rather than making a conceptual
analysis and a solid plan. The curriculum developed by Schoenfeld (1989) to help
students acquire attitudes and approaches towards learning mathematics and
solving math problems also serves as a good model for this context. Schoenfeld
developed a successful strategy to change this approach by dividing students into
small groups and tasking them to solve mathematical problems. While solving the
problems, Schoenfeld walked amongst them and asked questions like “What are you
doing?”, “Why did you choose this way?”, “Would this approach make you any closer
to a solution?” etc. Those students who were already accustomed to using formulas
performed a conceptual analysis and understood that they needed a good plan from
the start. This method applied by Schoenfeld helped many students gain effective
approaches towards problem solving in just a couple of weeks, and the students
began spending time on qualitative analysis and decision making before considering
the given equations (Collins et al., 1989; Schoenfeld, 1989).
Novice & expert problem solvers
Attitudes and approaches of expert and novice students towards problem solving
differ from each other. Expert/novice analysis in attitudes towards learning and
problem solving was employed by Chi, Feltovich, and Glaser (1981). The researchers
stated that novice students mostly used different methods in solving physics
problems; while experts classified problems according to the principles that manage
the process, novice students classified according to the superficial structures of the
problems.
There is a general need for understanding both difficult questions that require
more than just recall and simple structures that enable students to solve the
problem. Within the study process, expert students, who are mostly undergraduates
© Author(s), International J. Sci. Env. Ed., 11(5), 819-837 821
M. Duran
and postgraduates, are compared with novice students taking the course for the first
time (Smith & Good, 1984). Whilst results are achievable (Camacho & Good, 1989), it
is, however, also possible to encounter researchers comparing performances of
experts who examine routine exercises and novice students who study on new
problems.
Larkin and Rainard (1980) divided physics problems through classifications of
novice and expert students. Novice students start the process by determining the
aim of the problem through a means-ends analysis; finding the difference between
the aim and the available information and an equation that may decrease the
difference, and then applying the equation. Expert students, on the other hand, use
knowledge-development or forward-chaining approaches by starting with the
information given in the problem and conducting the processes until they achieve a
result.
As an alternative to the study on being expert or novice, another research was
conducted on the comparison between “expert” and “novice” students. In a study
conducted on the performances of high school students solving problems with
chemical equations through the HyperCard method (Kumar, 1993), “expert”
students were chosen from honor students and “novice” students from normal
chemistry classes. Heyworth (1999) supposes another approach that divides
students as experts and novices through a paper and pencil test. Students who had
not made any calculation errors and had understood the concepts were determined
as “experts”, while those who made errors and lower comprehension of concepts
were classed as “novices”.
Benner (1984) supposes in his study about clinical nurses that the difference of
“to know what” and “to know how” can be determined with experience in favor of
the latter, as experience is a prerequisite for expertise. According to Elio and Scharf
(1990), in terms of physics problems, experts are not actually those who know more
than novices; the only difference between them is the way they organize their
knowledge in a field and whether or not they apply this knowledge in problem
solving.
As for this current study, the 10th grade students can be regarded as the
“novices”, as they do not possess the adequate experience in chemistry problem
solving and have not encountered difficult questions, except those tackled during
their chemistry course in the 9th grade. By comparison, the 11th grade students and
university undergraduates may be expected to be more expert-like due to their
relatively higher level of experience in the field; however, it should also be stressed
that, as some of the researchers mentioned have also stated, expert-like attitude is
not achieved by simply taking more courses or from having more experience, but
from the approach of the student towards the question and the skills gained in order
to develop problem solving methods and strategies.
Significance of study
There are many studies within the literature about secondary school, high school
and university students in terms of their attitudes towards chemistry. This current
study will focus on high school and university students’ attitudes and approaches
towards solving chemistry problems. The lack of such studies found in the literature
and the comparison made between attitudes and approaches of high school and
university students, brings this current study to prominence. Another characteristic
of this current study is that it also examines the approaches and attitudes of the
same students towards physics by implementing the AAPS scale, and compares the
results with others obtained through the analysis on chemistry. Moreover, adapting
a scale originally developed for physics to chemistry would be guiding for future
822 © Author(s), International J. Sci. Env. Ed., 11(5), 819-837
Students’ attitudes and approaches to problem solving in chemistry
studies in science education, as it may be a model for future interdisciplinary
studies.
Research questions
How do students’ attitudes and approaches differ toward solving chemistry
problems? Throughout the study, we will seek answers to the following questions;
 Is there any difference between male and female students in terms of novice-
like and expert-like attitudes and approaches towards solving chemistry problems?
 Is there any difference stemming from types of high-schools in terms of
students’ novice-like and expert-like attitudes and approaches towards solving
chemistry problems?
 Is there any difference between high school and university students in terms
of novice-like and expert-like attitudes and approaches towards solving chemistry
problems?
 Is there any difference between chemistry and physics courses in terms of
students’ novice-like and expert-like attitudes and approaches towards solving
problems?
METHOD
Participants
This research was conducted in Ankara and Yozgat, two geographically different
cities in Turkey. Two of the six participant schools are regular high schools, two are
science high schools, and the other two are vocational high schools. As these sample
schools represent the whole population of the study and present better accessibility
for the researchers, these cities were chosen as the area of study. In addition, the
chosen university is where the researcher is currently lecturing.
Types of high schools within this study are regular, science and vocational, with
student placement according to scores of a national exam. The most successful
students have the chance to study at a science high schools. Science high schools are
the most preferred, as studying at these schools means a pretty much guaranteed
future for the students. The number of weekly compulsory science courses is higher
at science high schools than for other high school types. Regular (Anatolian) high
schools are the most widespread high school type in Turkey and the second most
preferred high schools after science high schools. History, geography and literature
courses are also given at these schools in addition to mathematics and science. In
these schools, students are divided into categories and the number of science or
social sciences courses is determined according to these divisions. As for vocational
schools, science and mathematics courses are obligatory, but at a reduced level. In
addition, there are also different courses such as ICT, electrical science and
electronics, food technology, technical drawing, library science, logic, sociology, and
science of religion. Chemistry courses are given in two course hours for 9th grades of
all school types as a compulsory course. This number increases to five hours in 10th
grade classes of science high schools, and up to seven course hours (three obligatory
and four elective) in the 11th and 12th grades. Regular high schools give this course
as two hours obligatory for 10th grades, and four hours elective for 11th and 12th
grades. Vocational schools, on the other hand, give two hours of science courses to
10th grade classes and three hours to 11th and 12th grades, both as an elective course.
There are 36 weeks in an academic year of high schools. The same chemistry
curriculum is implemented across all high school types. The curriculum, course
books and subsidiary sources that are used in schools are prepared or certified by
the Ministry of National Education. One regular (Anatolian) high school and one

science high school within this current study are private schools, rather than state
schools. Private schools implement the same chemistry curriculum prepared by the
Ministry, but may act independently in terms of subsidiary sources and materials,
and may use additional books and materials.
The participant university students are currently in their first year of the science
teaching department in the Faculty of Education, working towards a career as
science teachers in secondary schools. Most of the undergraduate students have
graduated from regular high schools, having taken mathematics, physics, chemistry
and other obligatory courses, and passed the Transition to Higher Education
Examination (YGS), answering questions predominantly about science, mathematics
and literature. The AAPCS scale was implemented to all students at the end of the
2014-2015 academic year. The subjects of chemistry that university students
learned during their study are the physical and chemical properties of matter,
chemical reactions, aqueous solution reactions, gaseous state of matter, chemical
kinetics, thermochemistry, quantum theory and atomic structure, chemical
equilibrium and acids and bases. High school students, on the other hand, learned
acids-bases-salt, mixtures, industry and biological energy, and chemistry in
everyday life in the 10th grade; then chemical reactions and energy, chemical
kinetics and equilibrium, equilibrium in aqueous solutions and electrochemistry in
the 11th grade. Demographic details about the 522 participant students are given in
Table 1.

According to Table 1, it is seen that demographic data for some participant
students are not included in this dataset. These students were excluded from the
analyses (e.g., the 10 students, whose grade levels are not specified were excluded
from the grade level analysis).
Survey instrument
The scale, originally developed for physics course, was adapted for chemistry.
The adapted AAPS instrument was prepared by Mason and Singh (2010) based on
the Maryland Physics Expectation Survey (Redish et al., 1998), as developed by Marx
and Cummings (2007) and Cummings, Lockwood, and Marx (2004) with the
purpose of identifying students’ epistemological beliefs towards learning physics for
the first time. Its validity has already been verified, having been implemented for
many beginner and advanced physics students in the United States.
Chemistry and physics, which are two different branches of science, basically
analyze the structure of matter and closely interact with each other and face many
similar problems. The only difference is in their perspectives and approaches. These
two branches of science are at close quarters in certain fields such as physical
chemistry, quantum mechanics, nuclear physics/chemistry, material science,
spectroscopy, solid state physics, crystallography and nanotechnology. Common
subjects of obligatory physics and chemistry courses are; the physical and chemical
properties of matter, solid, liquid and gaseous states of matter, atomic theories,
thermodynamics, and quantum chemistry. The attitude and approach scale of
physics was able to be adapted to chemistry due to the similarities between the
course subjects. The scale prepared for the chemistry course included 31 items after
omitting two items (numbers 32 and 33). The survey questions are organized in the
form of statements that one could agree or disagree with on a scale of “1” (strongly
agree) through to “5” (strongly disagree), with “3” signifying a neutral response. The
items of AACPS are worded such that while for 22 of them, “strongly agree” and
“agree” are favorable responses, for nine items “strongly disagree” and “disagree”
are favorable responses (expert-like responses).

As an example to the changes in the AAPS physics scale, the item “If I cannot solve
a physics problem in 10 minutes, I give up on that problem” was changed to “If I
cannot solve a chemistry problem in 10 minutes, I give up on that problem”. Both
items were not difficult to answer for both chemistry and physics. In addition, we
see that some other attitude scales in the literature were also adapted for the
chemistry course such as Tamir et al. (1974).
Examples about favorable (expert-like) and unfavorable (novice-like) answers
were given and the expert-like answers were also stated in parentheses:
 If I cannot solve a chemistry problem in 10 minutes, I give up on that
problem, (expert-like responses; “disagree somewhat”, “strongly disagree”). The
answers; “agree somewhat” or “strongly agree” were regarded as “novice-like”
answers.
 When I have difficulty in solving a chemistry homework problem, I like to
think through the problem with a peer, (expert-like responses; “agree somewhat”,
“strongly agree”). If the answer was “disagree somewhat” or “strongly disagree”, it
was accepted as “novice-like”. The details about novice-like and expert-like
questions can be seen in the study of Mason and Singh (2010).
Validity and reliability
In order to ensure validity of the instrument, the first version of AAPS scale which
had been prepared and developed in English was translated into Turkish with the
help of experts within the field of science, and then some students were asked to
read the scale in order to check the language correctness. The translation was made
by three experts in science teaching and an expert translator who has specialized in
this field. Then, the translated texts were checked by two instructors who normally
give lessons for university preparatory classes. After that, these translations were
sent to the researchers who had developed the original scale and these researchers
then asked two other researchers who are native Turkish living in United States, and
they also agreed on correctness of the translations.
Secondly, completing the translation of the AAPS scale, the questions were given
to five high-school students from different schools who were asked to read and
interpret the questions. It was important to take feedback from the schools which
are within the scope of the study so as to determine whether or not there were
concepts or words with which students were not yet familiar. Students were also
asked to write notes on any questions they found difficulty with, or were simply
unfamiliar to them. Two students from the 10th grade stated that they could not
understand the 7th question as it was too long. The researcher made the necessary
changes to the question in order to make it shorter and more comprehensible. On
the other hand, two university students were asked to read out the questions one by
one and think aloud, in order to determine whether or not they had difficulties in
understanding. Both of the students completed the questions without any problems
in either reading or understanding them. Therefore, the items were finalized, and

M. Duran
written in an understandable format ready to be implemented to the selected
students of the participant high schools and university.
Thirdly, the scale was conducted at the end of the 2014-2015 academic year. It
was applied to high school students by chemistry teachers within the last 20
minutes of course hours. Five more minutes were given to students who could not
complete the scale within the allotted time. As for the university students, they were
able to complete the scale within 20 minutes as the researcher was their own
instructor. It was expressed to the students that the scale had been prepared in
order to enhance the quality of chemistry teaching, they were free to choose
whether or not to answer anything, that they would not be penalized if they did so,
but most importantly, their answers had to be honest. All of the students were eager
to participate in the study and did not ask for any help throughout the process. It can
be inferred therefore, that the adapted scale was easily understandable and did not
include any mistakes in terms of translation.
Finally, having collected the data, the Cronbach alpha (α) value was measured in
order to identify reliability of the scale in terms of internal consistency. α values of
different groups are shown in Table 2 (gender, school types, and grades). It is seen
that the Cronbach alpha values are above the admissibility level (0.70<α<0.86).
Data analysis
Variances were analyzed item by item through descriptive and inferential
statistics. Normalized datasets were used for the descriptive statistics. In order to
standardize the data, favorable, unfavorable and neutral responses were assigned
with “+1”, “-1” and “0” values respectively. As a result of this process, each
participant was scored between -1 and +1 for each item. In the following section, we
will primarily give standard statistics about differences between gender, grades, and
school type and offer the most significant results. After a general analysis of
differences between total scores of groups, the items will be examined through a chi-
square test.
Within the process of analyzing the data, it was considered appropriate to apply
the Factorial ANOVA test in order to analyze the effects of gender, school type, and
grade on students’ attitudes and approaches towards chemistry problems. However,
one of the assumptions of the Factorial ANOVA was unable to be met. The “Levene's
Test of Equality of Error Variances” showed that the error variance of the dependent
variable (students’ scores) was not equal across groups. For this reason, a non-
parametric test, chi-square test was implemented instead. The study will try to find
out whether or not there are statistically significant variances between the
responses of different groups (males vs. females, regular high schools vs. science
high schools or universities) using the results to be obtained through the chi-square
test and the AACPS scale. Likewise, the chi-square test will be used in order to reveal
whether or not there are statistically significant differences between the questions
given in the AACPS/AAPS scales about chemistry and physics courses.

RESULTS
The data obtained was classified according to grade and school type. As the
gender and levels of classes were composed of sub-groups, the differences between
the groups were analyzed through the t-test. Moreover, there were four different
types of schools, and to analyze the difference between mean scores ANOVA was
implemented, and Benforroni analysis was conducted as Posthoc analysis.

Figure 1. Percentages of favorable, unfavorable and neutral responses of different groups.

Total percentage values of some groups are not equal to 100 because of blank or
incomplete responses. Error bars were calculated by standard errors of each group.
As suggested in Figure 1, the numbers of favorable responses for each group were
found to be more than the unfavorable responses.
When Figure 1 is examined in terms of gender differences, we can see that
favorable responses of female students are more than male students, while
unfavorable responses of females are less than males. When the whole AACPS scale
is analyzed through the t-test, we see a significantly higher number of average
scores in females compared to males (t=3.47, df=546, p=0.001). The t-test conducted
on the basis of grade levels, on the other hand, shows that responses of 10th grade
students are more expert-like than the 11th graders (t=3.83, df=505, p=0.00).
The analysis of school types indicated that the percentages of university students’
expert-like responses are higher than other groups (52%). Percentages of science
high school students’ expert-like responses were found as lower than university
students (45%), while expert-like responses of vocational high school students were
calculated as the lowest value (42%). The ANOVA test was applied in order to
examine differences between groups in terms of favorable responses. The ANOVA
tests conducted in all types of schools, including universities, indicated significant
differences among the groups (F=6.54, df=3, p=0.00). Through the Bonferonni
analysis conducted to find out the group differences, a significant statistical
difference was found between university and high school students. However, no
difference was found among different types of high schools.

Descriptive analysis for survey items
In this section, total values will be analyzed, considering students’ responses for
each survey item. Within the analysis, favorable, unfavorable and neutral responses
given to each question were assigned with +1, -1 and 0, respectively. Therefore, if
the number of a student’s responses assigned with “+1” is higher than ones assigned
with “-1”, responses will be regarded as expert-like. Standard scores of groups for
each item were obtained by dividing the total number of responses by the number of
positive (+), negative (-), and neutral (0) responses. The standard scores given in
Table 3 indicate the total average of students’ responses to each question,
considering the gender differences. The first value from Table 3 is an example of this
situation; if we add 80 positive, 204 negative and 72 neutral responses, we get (= -
124), and then we divide this number by the total number of responses of male
students (356), we will get the result as -0.35. Likewise, the positive (+) results
show that favorable responses are more than others in number.
Table 3 shows average scores of students’ favorable and unfavorable responses
for each item, considering the gender differences. According to these results;
unfavorable responses of males were more than favorable responses in eight items
(01,03,05,11,12,16,23,30), while this number was nine (01,03,05,11,12,17,23,30,31)
for female students. On the other hand, both male and female students’ unfavorable
responses were more than favorable in seven items. It is also seen that the average
favorable responses of female students to 16th item was far more than for males.
Female and male students gave more expert-like answers to the 29th item with
average scores of 0.74 and 0.47 respectively. Towards the question about homework
given as the 20th item, male students’ responses were interestingly neutral, while
females’ were rather more favorable. The maximal novice-like attitude and
approach of all students were for the 12th item, with average scores of -0.56 and -
0.42 in females’ and males’ groups respectively.
Table 4 indicates the average standard scores of high school and university
students’ favorable and unfavorable responses. We firstly understand that students’
unfavorable responses to the 5th, 11th, and 12th items in all school types, rather than
favorable ones. It means that students of all types of schools gave novice-like
